A nice addition to Microchip’s LDO line, which once suffered from a lack of high voltage output LDOs. The MCP1804 is a 28V, 150 mA LDO family. The wide input operating voltage range allows the MCP1804 LDO to be used with standard 12V and 24V power rails, and it’s wide output voltage range, available from 1.8V to 18V, provides greater design flexibility. The MCP1804 LDO is ceramic capacitor stable down to the low value of 0.1 μF, allowing for smaller sized ceramic capacitors. This helps to reduce space and cost. Available packages include 3-pin SOT-89 and SOT-223, as well as 5-pin SOT-23 and SOT-89, which feature a shutdown pin to lower current consumption to just 0.01 microamperes.
